Syncthing is very good, but the best iOS implementation, Möbius Sync[1], is not comparable with the Android one (the OS limits the syncs, you need a regular notification and so on).

The great things about Logseq are his weakness for me. Everything is so interconnected (you can say: "here put the paragraph of this other note") that I sometimes lose confidence in the system. It becomes too complex. With Obsidian I know that a note is a file. Less convenient but simple and reliable.

Logseq really excels with his outlining mode, I miss it (but I don't like the way it saves states in the markdown file). It has some problems with the code blocks too.

Can you elaborate on the syncing part? Last I tried Logseq, syncing across devices via iCloud was very unreliable. So I gave up. Although I would have loved to replace Roam with Logseq back then. Now I stick to Emacs + orgmode and Obsidian for plain markdown files.

I have a folder in syncthing called "logseq". This folder holds the logseq files. I have logseq-sync on my phone so it syncs the folder. I also have a Cloudserver which is the spoke and all other devices (2 laptops, the phone) sync it.
